Electrical characteristics Frequency 50/60 Hz Voltage 100 - 127 / 200 - 240 VAC, rated Current 2.5/1.3 A Maximum power rating 222.9 W Idle power 24.4 W PoE power 185 W PoE+
Notes Idle power is the actual power consumption of the device with no ports connected. Maximum power rating and maximum heat dissipation are the worst-case theoretical maximum numbers provided for planning the infrastructure with fully loaded PoE (if equipped), 100% traffic, all ports plugged in, and all modules populated. PoE Power is the power supplied by the internal power supply, it is dependent on the type and quantity of power supplies and may be supplemented with the use of an External Power Supply (EPS).
